China says it 'firmly opposes' any plans for Pelosi to visit Taiwan next month. She'd be the highest-ranking US official to visit in decades.

If Pelosi's visit to Taiwan eventually happens, it would not be a miscalculation but an intentional provocation by the US. The US does not formally have any diplomatic relations with Taipei, but they do have formal diplomatic relations with China, and a visit to Taiwan would contradict the One China Policy and threaten PRC sovereignty.
As a global champion of democracy and human rights, it is only right that the US should support Taiwan and its democratic government. Any tension or military conflict caused by a visit by Speaker Pelosi to the island would be an outlandish escalation on China's part.
